Red flags

  • Keytruda represented 49% of total 2025 sales, creating substantial single-product concentration risk.
  • Sales were nearly flat in 2025 at $65.0 billion, up only 1%, while the company faces several large product losses in 2026 and expects Keytruda pressure from biosimilars beginning in late 2028.
  • Merck had approximately 610 pending Dr. Scholl’s foot-powder product-liability cases and approximately 135 pending Gardasil/Gardasil 9 cases as of December 31, 2025.
  • Merck states it has no insurance for most product liabilities because the cost of available coverage outweighs the expected benefits.
  • Long-term debt rose to $46.75 billion at year-end 2025 from $34.46 billion, alongside the $8.0 billion debt issuance in December 2025.
